I'm currently working on a bridged openvpn setup between two places. My home lan uses a 192.168.1.x subnet, as does the remote location (which i can't change the subnet for anyway) which results, naturally in ip address conflict. I'd like to know how i could change my home subnet to 192.168.0.x so that they wouldn't conflict.
With a bridged VPN then both endpoints must have the same subnet. You just have to ensure that each end uses different IP addresses (I would suggest that one uses addresses ending in
To change the subnet used for the LAN on a DD-WRT device log in to the web interface, select the Setup tab and change the settings under Network Setup. This, and much more, is covered in the DD-WRT documentation.
What version of DD-WRT are you running? It's certainly there in V24 and something similar should be there for V23.
Right, under Basic Setup you'll see Network Setup. That's the default tab as soon as you select Setup so I didn't see the need to highlight it.
Changing the Local IP address is what you want. Changing the Subnet Mask changes what bits of the Local IP address field are interpreted as the local network, which won't help you.
You can setup a virtual subnet which enables something like this:
Since the process is a lengthy one, I won't post what to do, but I found this tutorial on how to do just that.
In case that one doesn't work here is a second one to go off of.
Update After reading the tutorials a little more, it looks like the second one, might be a little more successful, but I'll leave both up.
The simplest idea is to use fixed IP addresses.
For example, give your home computers an IP address that counts down from 192.168.1.253.
